Convulsion in the aged.
The convulsion and electroencephalographic patterns were examined on 2,625 subjects aged 60 and over. Of these, 2000 were consecutive autopsy cases. convulsion was noted in 4% of the 2,625 cases and the incidence of epilepsy was 0.076%. In 26.4% of 72 cases with cerebrovascular disorders who died during the past two years, convulsion was found, and the value indicated a remarkable increase compared with the previous report. Convulsion was noted most frequently in the acute state of cerebral apoplexy and myoclonus was most common. The prognosis of such cases was poor. The incidence of convulsion in 30 consecutive patients with brain tumor was 13.3%. On 20,000 electroencephalograms, the incidence of the typical spike and wave complex was less than 0.005%. No 6 and 14c/sec positive spike was recognized.
